The European Union (EU) is determined to find integrated solution for common problems like environmental challeges and water management. Finding solution for common challenges requires trust and cooperation from every actor involved. This is the basic principle of EU on the question of water management. Meanwhile, an effective handling of the same problem requires stong cooperation and unity in execution that is the adoption of the same goals is not enought, the administration also needs some kind of interrelation. However, the difference in competences of EU legislation on these different but strongly attached legal areas can lead to an insignificant result or just degrade the efficiency of the cooperation. The paper aims to reveal the mass lofty goals and their realisation in the view of administrative reality and future prospects in a Hungarian point of view.
